Through the technical scheme, finger operation operating parts 1 motion, it removes to drive elasticity piece 3 that resets, the operating force with the finger transmits to micro-gap switch 4, thereby make micro-gap switch 4 take place the action of intercommunication or disconnection, no longer exert force when the finger, micro-gap switch 4 takes place the action back swift resilience and resets, the finger can definitely experience operating parts 1 and receive micro-gap switch 4 resilience effect and reset, the feedback of clear perception on-off information, the reliability is high, elasticity piece 3 that resets can cushion micro-gap switch 4's swift resilience, avoid this resilience direct transmission to feel for the puckery that operating parts 1 brought, thereby improve the travelling comfort of feeling when operating parts 1. Therefore, the switch structure is comfortable to operate and high in reliability.

Specifically, the operating member 1 is accommodated in the mounting groove, is operated by a finger to move relative to the switch panel 6, and is reset by the resilient force of the micro switch 4 and the resilient force of the elastic reset member 3 after the finger is no longer applied with force. Wherein, the microswitch 4 can be selected from a press switch with smaller stroke and quick rebound, which is beneficial to the fingers to clearly feel the action of the microswitch 4. Return rubber can be chooseed for use to elasticity piece 3 that resets, is kick-backed rapidly after being compressed to in the resilience force that produces resilience force and transmission micro-gap switch 4 fast acts on operating parts 1, makes the finger can definitely feel micro-gap switch 4's break-make information, promotes the operation and feels, and in addition, the setting of return rubber can reduce or avoid the noise between operating parts 1 and micro-gap switch 4.

According to some embodiments of the present disclosure, the operating member 1 may move up and down, slide back and forth, or rotate with respect to the switch panel 6 when operated. Specifically, the mounting groove may be a through hole extending in the up-down direction formed on the switch panel 6, the operating element 1 moves up and down in the through hole under the action of the finger operating force, the elastic reset element 3 is connected with the operating element 1 and moves up and down under the driving of the operating element 1, so that the finger operating force is transmitted to the elastic reset element 3 to act; or, the mounting groove may be a rectangular groove formed on the switch panel 6 and extending in the front-back direction, the operating element 1 may slide back and forth in the groove, an opening is formed on the bottom wall of the groove, the operating element 1 is connected with the elastic reset element 3 through the opening to drive the elastic reset element 3 to move, and the front-back direction herein refers to any direction parallel to the plane of the switch panel; alternatively, the operation element 1 rotates relative to the switch panel 6 around the inner diameter of any one of the front and rear directions in the mounting groove.

According to some embodiments of the present disclosure, as shown in fig. 1, the elastic restoring member 3 may be formed in a cover shape with an open bottom to cover the micro switch 4 in a shape-fitting manner. Like this, elasticity resets and can cover at micro-gap switch 4's surface, laminates mutually with micro-gap switch 4, and elasticity resets and all can transmit to micro-gap switch 4 reliably the effort that 3 received, and elasticity resets and 3 cover on micro-gap switch 4, can protect micro-gap switch 4, avoids it to receive the influence of external dust, water and breaks down.

According to some embodiments of the present disclosure, as shown in fig. 1, the lower end of the micro switch 4 may be connected to the circuit board 5, and the elastic restoring member 3 may extend downward and be sealed to the circuit board 5 to cover the micro switch 4. Wherein, micro-gap switch 4's lower extreme fixed connection is on circuit board 5, elasticity resets 3 can downwardly extending and with circuit board 5 sealing connection, like this, elasticity resets 4 can wrap up micro-gap switch 4 completely, get into dust or moisture etc. in avoiding micro-gap of micro-gap switch 4 and the 5 junction of circuit board, wherein, elasticity resets 3 can extend to the limit portion of circuit board 5, and the limit portion of cladding circuit board 5, like this, whole circuit board 5 and micro-gap switch 4 all avoid the adverse effect of external dust or moisture. In addition, a plurality of micro switches 4 can be arranged on one circuit board 5, and the elastic reset piece 3 can be formed into a whole to coat the micro switches 4 and the circuit board 5.

Because operating parts 1 moves for flush mounting plate 6 under the effect of finger operating force to reset under the effect of micro-gap switch 4 and the 3 resilience forces of elasticity piece that reset, for avoiding operating parts 1 to move at will or even break away from for flush mounting plate 6, can set up anticreep buckle restriction operating parts 1, make it keep in corresponding position, can not rock at will or break away from in the mounting groove when receiving external forces such as vibration. The anti-disengagement latch may be of any suitable form, for example, when the operating element 1 moves up and down relative to the switch panel 6, the anti-disengagement latch may enable the operating element 1 to be always connected to the elastic reset element 3, avoiding the operating element 1 from moving freely between the anti-disengagement latch and the elastic reset element 3.

According to some embodiments of the present disclosure, when the operating element 1 is not operated, the elastic restoring element 3 is in a micro-pressure state. Like this, elasticity resets and 3 has the resilience force to operating parts 1 all the time for operating parts 1 can support in the anticreep buckle, avoids rocking one. The micro-pressure state means that the compression range of the elastic reset piece 3 is within 0.2mm, and it should be noted that the resilience force generated in the micro-pressure state is smaller than the acting force required by the micro-switch 4 to be connected or disconnected.
